EGW 1911 Mainspring Housing Arched Checkered – SS

EGW 1911 Arched Mainspring Housing

Checkered • Stainless Steel

Upgrade your 1911 with the EGW Arched Checkered Mainspring Housing, a premium component that blends classic styling with modern precision. Whether you’re completing a retro WWII-inspired build or replacing a worn factory part, this housing delivers improved balance, better grip, and long-term durability.

Classic Arched Design with Modern Performance

The arched profile naturally fills the hand and helps position the pistol consistently during every draw. As a result, many shooters experience improved pointability and a more secure firing grip. Additionally, the arched design complements classic 1911 aesthetics, making it an excellent choice for traditional or restoration-style builds.

25 LPI Checkering for Secure Grip Control

EGW machines crisp checkering into the housing to provide reliable traction exactly where you need it. Consequently, your grip stays firm during recoil, rapid fire strings, and reloads. At the same time, the checkering enhances control without feeling overly aggressive.

Premium Stainless Steel Construction

Unlike inexpensive cast alternatives, EGW machines this mainspring housing from solid bar-stock stainless steel. Therefore, it resists cracking, deformation, and wear far better than plastic or cast housings. Furthermore, the glass-beaded stainless finish delivers a clean, satin appearance while also improving corrosion resistance.

A Smart Replacement for Plastic Housings

Many factory 1911s ship with plastic mainspring housings. By upgrading to this EGW stainless steel version, you add useful weight to the rear of the pistol, which helps balance the gun and soften the recoil impulse. In turn, the pistol feels more stable and predictable in the hand.
